What are the best practices for using router guards in Vue.js?

When using router guards in Vue.js, it's important to keep your logic simple, avoid unnecessary complexity, and ensure that guards are reusable.

Can you give me an example of a simple router guard?

Sure! A simple router guard can check if a user is authenticated before allowing access to a route. You can use the beforeEnter guard like this:

const routes = [
  {
    path: '/protected',
    component: ProtectedComponent,
    beforeEnter: (to, from, next) => {
      if (isAuthenticated()) {
        next();
      } else {
        next('/login');
      }
    }
  }
];

What should I avoid when implementing router guards?

Avoid using too many nested guards, as they can make your routing logic hard to follow. Also, don't perform heavy computations in guards; keep them lightweight.

How can I test my router guards effectively?

You can test your router guards by writing unit tests that simulate navigation and check if the correct routes are accessed based on the guard logic.
